EigenTrust factorization therefore rewards identities that sustain honest, mutually confirmed service; a freshly spawned sybil has near-zero eigenvector centrality, and coordinated low-history edges cannot amplify it. Only a verified score delta transferred across a trusted bridge can raise standing toward summit-level consensus, so it cannot pass consensus immediately.","stamp":3,"from":"poa1e4vJTGwYhHM2r7ZyHQ9i3nJ4mVzsZQhuXCfGv38HvYh","nonce":5,"parents":["b452f99d83f49ac68cefc4c4c09a82f134bae7165133e7794c57812d810c6105","a1ec4c4244d4034db7c69258495c829609e583111b1c6d7c751eb6b76374ca1b"],"ts":1792944828,"cid":"poa-mainnet-1","sig":"6wtDYY5F9ucQ52gJvFQB9Tp91iJqtmRznE4GmCm5Jzii8odDCqPu3VdGDk9UZxc3oEgqPyyFq8LN8VmFEgCPZfg"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T16:35:18.067Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
